Abstract

Pour accroître l’inertie d’un becquet d’étanchéité d’aube pour turbomachine d’aéronef, et améliorer ainsi la durée de vie d’un tel becquet d’étanchéité, le becquet d’étanchéité (48) est conformé de manière à présenter un creux (98) dans sa surface externe (S2) et une bosse correspondante dans sa surface interne (S1), le creux et la bosse étant définis à partir d’une section transversale (60) de raccordement du becquet d’étanchéité à un corps d’aube (40), et étant formés à distance d’une extrémité axiale libre (62) du becquet d’étanchéité. Figure pour l’abrégé : Figure 7To increase the inertia of a blade sealing spoiler for an aircraft turbomachine, and thus improve the service life of such a sealing spoiler, the sealing spoiler (48) is shaped so as to have a depression (98) in its outer surface (S2) and a corresponding bump in its inner surface (S1), the depression and the bump being defined from a cross section (60) connecting the sealing spoiler to a blade body (40), and being formed at a distance from a free axial end (62) of the sealing spoiler. Figure for abstract: Figure 7
